Adjustment
The instrument is calibrated fully electronically and readjustment is not necessary.
Precautions
This is a risk of injury if the metal ball comes into a contact with live parts.
Use the instrument only for measuring the dampness in hardened building materials by bringing the ball into a
contact with the surface.
Do not take measurements on metallic linings.
Take measurements at distance 8-10 cm from the edge/recess.
Instrument check
Hold the instrument as near to the back as possible. Press the MEAS button and hold the instrument with the ball in
the air. The displayed value must be between -5 and +5.
Operation
Hold the instrument as near to the back as possible. Press the MEAS button and use the ball to scan the surface under
investigation. The ball must be in irm contact with the material. To obtain the best results, the instrument should be
held at angle of 90° to the surface to be measured.
If the icon appears on the LCD display, it indicates that the battery should be replaced. Open the battery case
and replace the battery with the new one.
